EDWARD W. GERBISH, OF LYNN, MASSACHUSETTS, ASSIGNOE OF ONE-HALF TO LAST COMPANY, OF LYNN, MASSACHUSETTS, A CORPORATION OF MASSACHUSETTS' HINGED LAST.

Application filed May 15, 1925. Serial No. 30,470.

This invention relates to divided lasts and has for its object the production of a whole last with continuous surfaces when extended, said last being divided on a curved line from the bottom to the top at a point to the rear of the comb thereofand the two parts be ing connected by a member anchored in the fore part and pivoted to the heel part.

This object is attained by the device illustrated in the accompanying drawing.

For the purpose of illustrating the invention, one preferred form thereof is illustrated in the drawings, this form having been found to give satisfactory and reliable results, although it is to be understood that the various instrmnentalities of which the invention consists can be variously arranged and organized, and the invention is not limited to the precise arrangement and organization of these instrumentalities as herein shown and described except as required by the scope of the appended claims.

Of the drawings Figure 1 represents a-vertical section of a last embodying the principles of the present invention, and

Figure 2 represents a front elevation of the heel part and showing the connecting member in section.

Similar characters indicate like parts throughout the several figures of the draw' ings.

In the drawings, is the fore part and 11 the heel part of a last divided by a curved cut 12 extending from the bottom at 18 to the top 14 at a point to the rear of the comb 15.

The heel part 11 is provided with the usual pin socket 16 and has extending transversely thereof the pivot pinl'l which is at the axis of the curved out 12 and projects through one end of the connecting member 18, the opposite end 19 of which is cylindrical and threaded to the fore part 10 as shown in Fig. 1. I

"When the member 18 has been properly positioned in the fore part a pin 20 is driven through the fore part 10 and an opening in the threaded end 19 to prevent the turning of the member 18 about its axis.

By this means the member 18 is securely anchored in the fore part 10 with one end projecting rearwardly therefrom into the slot 21 in the heel part 11, this projecting ,surfacesof which are continuous and the comb of which is unbroken, and yet when it is desired to insert the last into a shoe or remove it therefrom it may be shortened to permit these operations to be performed.

In shortening, the member 18 is moved about its pivot 17 against the tension of the spring 23 in the opposed grooves 24:.

It will be noted that when the spring 23 is once installed, it is thereafter hidden from view, the grooves 24 and slot 21 being closed by the rear wall of the fore part 10.

In shortening, the rear bottom corner 25 of the heel part 11 will move in the path indicated by the dotted line 26. A pin 27 prevents displacement of upper end of spring 23.

This makes a very simple but effective last, particularly adapted for use in lasting the open work pumps now extensively worn by women and girls.

It is believed that the operation and many advantages of the invention will be understood without further description.

Having thus described my invention, I claim:

1. A last divided into a fore part and a heel part by an arcuate cut extending upwardly and rearwardly from the bottom to the top at a point at the rear of the comb; a connector immovably anchored in the fore part and pivoted to the heel part; and a spring disposed in an arcuate groove formed in the front face of the heel part and coacting with said connector to retain the last extended, said groove at all times being covered by the rear face of the fore part.

2. A last divided into a, fore part and a heel part by an arcuate cut extending from the bottom to the top at a point at the rear of the comb; a connector screwed into the fore part with a rearward extension pivoted to said heel part; and a spring disposed in an arcuate groove formed in the front face of the heel part and coacting with the upper edge of said connector to retain the last extended, said groove at all times being covered by the rear face of the fore part.

3. A last divided into a fore part and a heel part by an arcnate cut extending from the bottom to the top at a point at the rear of the comb; a connector inserted into the fore part and fixedly secured thereto by being pinned thereto with a rearward extension pivoted to said heel part; and a spring coacting with the upper edge of said connector to retain the last extended, said heel part having a recess in its front face to receive said spring, which recess is at all times covered by the rear face of the fore part.

4. A last divided into a fore part and a heel part by a cut extending from the bottom to the top at a point at the rear of the comb; a connector inserted into the fore part and immovably pinned thereto with a rearward extension pivoted to said heel part; and a helical spring interposed between a shoulder on said heel part and the upper edge of said connector to retain the last extended, said spring at all times being covered by the rear face of the fore part.
